Subject: [PATCH] GRETH: added greth_compat_mode module parameter
|
|
|
|
The greth_compat_mode option can be used to set a GRETH GBit capable MAC
|
|
in operate as if the GRETH 10/100 device was found. The GRETH GBit supports
|
|
TCP/UDP checksum offloading, unaligned frame buffers, scatter gather etc.
|
|
Enabling this mode allows the developer to test the GRETH 10/100 device
|
|
without all features mentioned above on a GBit MAC capable of the above.
